Answer:
A patient with a spinal cord injury that resulted in paralysis of the legs has paraplegia (option c).
Explanation:
Paraplegia consists of paralysis of the lower extremities or legs due to injuries to the spinal cord, from the dorsal vertebrae. Other causes of paraplegia include tumors and malformations that affect the spinal cord.
<u>The spinal cord provides the nerves that allow the innervation of the limbs</u>. A spinal cord injury interrupts communication between the brain and the effector (motor) muscles as well as the sensory nerves in the affected limbs, producing paralysis. When it occurs in the legs is called paraplegia.
The other options are not correct because:
a. Hemiplegia corresponds to paralysis of upper and lower limbs on one side only.
b. Pseudoplegia is a paralysis that is due to mental disorders such as conversion disorder, without injury to the nervous system.
d. Dysplegia is associated with motor disorders observed in children with varying degrees of dysfunction or cerebral paralysis.
Answer:
Adenosine.
Explanation:
Adenosine is a neurotransmitter that is created in the brain and when it binds to the adenosine receptors, it slows down nerve activity and it creates a sensation of drowsiness.
<u>Caffeine</u> looks like adenosine to the receptors, therefore, when we have caffeine, <u>it binds to these receptors and there is no room left for the adenosine to bind</u>. However, the caffeine doesn't slow down nerve activity but, in the contrary, it speeds it up.
Therefore we can tell that caffeine blocks the receptors for the adenosine thus promoting wakefulness.
